MEANS FOR GONTROLLING FIBER-TREATING MACHINES.

Application filed October 8, 1913.

To atl whom t may concern.'

Be it known that we, CHARLES M. GRnIs- ING and WALTER E. 4NArLoR, citizens of the United States, and residents oit' St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Means for Controlling F iber-Treating Machines, of which the following is a full, clear, and exact specification.

rlhis invention relates to mechanism for removing waste particles from fiber or other materiall out of which twine is made, and more particularly to means for controlling the operation for such mechanism.

In the manufacture of twine the liber or other material out of which twine is made is passed through various preparing, spinning and balling machines. While being fed into and in passing through such machines ieces of liber fall from the machines and colriect on the floor. At the same time .more or less dust is liberated from the ber as it passes through such machines. Most of this dust is drawn out through a suitable exhaust system, but some or' the dust collects on the ioor and becomes mixed with the fiber which has fallen onto the floor around and under such machines. Were this dust laden fiber thrown away, immense financial loss would result. To avoid such financial loss and to use all of the liber, this dust laden fiber is gathered from the various machines and put through a cleansing process in which all of the dust is removed from the fiber. The mechanism used for removing the dust includes a shaker and a picker. Shakers and pickers have been used for some time, but have been operated in such a way that fiber which has not been thoroughly cleaned has been tossed into the picker from the shaker at a time and 1n many instances when the picker was not in the roper stage of operation to receive such fiber. In other words, the picker would receive the dust laden fiber from the shaker and discharge same without completing the cleansing process of the fiber. Under these conditions the liber might not and more likely would not pass out of the picker in a clean condition. The fault resided in the fact that the operation of the coperative shaker and picker was not properly controlled.

serial No. 794,137.

It, therefore, is the object of our invention to control the operation of coperating shakers and pickers in a manner such that the fiber passing through such shakers and pickers will be thoroughly cleaned before passing from the latter.

This object is accomplished by providing in combination a shaker, a pickel', and means for controlling the opera-tion of said shaker and picker in a manner to obtain the desired result.

The invention is illustrated on the accompanying sheets and drawings in which- Figure 1 is a side elevation of a picker and a portion of a shaker embodying our inventlon Fig. 2 is a fragmentary side elevation of the same shaker;

Fig. 3 is a plan view of the shaker, picker, and control mechanism shown in elevation in Fig. l;

Fig. 4 is a side elevation of the control mechanism proper;

Fig. 5 is an end view of the same, parts being shown in section;

Figs. 6 and 7 are side and end elevations respectively of a cam member formi-ng a. part of the control mechanism shown in Figs. 4 and 5;

Fig. 8 is a sectional view of part of the transmission system by means of which motioi is transmitted to the control mechanism an Fig. 9 is a plan view of one end of the shaker showing means for conveying dust laden liber to the shaking members, and means for controlling the quantity of supply of said ber to said shaking members.

The various novel features of our invention will be apparent from the description and drawings, and will be particularly pointed out in the appended claims.

The mechanism herein considered, generally speaking, includes a shaker 10, picker 11, and control mechanism 12 associated with the picker 11 for controlling the oper ation of said shaker and picker. The shaker (reference being had particularly to Fig. 2) includes a box-like structure 13 in .which two shaking members 14 and 15 are actuated, said shaking members taking the form ot' movable grates through which dust may pass from fiber or material shaken thereon. The shaking member 14 is actuated by means of beams 16 pivotally connected at one end to shaking member 14 and at the other end connected with an actuating shaft 17 by means of eccentrics 18. As the shaft 17 rotates the shaking member 14, which is supported by rods 19 pivoted to the main frame at 20, is given a reciprocatory motion. In a similar manner the shaking member 15 is actuated, the only difference being that the shaking member 15 is located beyond and below the first shaking member 14. The actuating shaft 17 is provided with a loose pulley 21 and a tight pulley 22, which are alternatively engaged by a belt 23 connecting said pulleys ,with any suitable driving source. The shaft 17 is also provided with a pulley 24 around which passes a belt 24a, which is crossed and passes over another pulley 25 mounted upon one end of a shaft 26, upon the other end of which is secured a gear wheel 27 meshing with a relatively large gear 28, the latter being mounted upon one end of a shaft 29, to the other end of which is secured a sprocket wvheel 30. Passing around said sprocket wheel 30 is a chain 31 which passes over another sprocket wheel mounted upon one end of a shaft 33 upon which is mounted a feed'controller or kicker 34 which is adapted to control the quantity of supply of dust laden liber deposited in a pit portion 35 and conveyed therefrom past said feed controller and upon a conveyer band 36 to the'lirst shaking member 14. This conveyor band 36 passes around a roller 37 and a roller 38, the latter of which is mounted upon the shaft 29. rlChe feed controller 34 which rotates in a counter clock- ,wise direction,as viewed in Fig. 2, may be adjusted with respect to the conveyer band 36 by any suitable mechanism 40 to vary the quantity of supply of dust laden fiber fed from pit 35 onto the shaking member 14. llVhen the beltI 23 is on the tight pulley the Vshaking members 14 and 15 therefore being actuated, dust ladenV fiber which has been deposited upon the shaking membei` 14 is shaken or .fibrated-thereon for removing dust from saidv lfiber. This shaking movement of the member 14 causes the fiber to be tossed gradually along the grating of member 14 toward the shaking member 1a upon which it is eventually deposited to be shaken further. Dust which has been shaken from the fiber falls upon the floor 41 of the shaker and is scraped therefromby a conveyer 42 into a pit 43 in which a conveyer screw 44 is actuated from any suitable source for carrying away the dust to a furnace (not shown). The conveyer 42 includes chain members 45 which pass over a gear wheel 46 mounted upon the shaft 47 at one end of the shaker 10 and over another gear wheel 48 mounted 'upon a shaft 49 at the extremeopposite end ofthe picker 11. Motionis transmitted to this Vconveyer 42 by means including a sprocket wheel 50 mounted upon one end of shaft 49, chain 51 passing over said sprocket wheel and another sprocket wheel 52 mounted upon a stud shaft 53, upon which also is mounted a pulley 54 which may receive motion from any suitable source.

The picker 11 proper includes two rota tively mounted'wheels 55 provided with pins or spikes 56 which carry the fiber around for beating dust out of the same. rllhese wheels are mounted upon shafts 57 and are rotated in opposite directions by means of a crossed belt 58 which passes over pulleys 59 and 60 mounted on said shafts, one of said shafts having a pulley 61 which is adapted to receive motion from any suitable driving source. Mounted below the picker wheels 55 is a curved grating 62 through which dust passes and is conveyed away by the same conveyer 42 to the conveyer screw 44, The picker is provided with a door 63 (see 3, 4 and 5), through which the fiber passes after it has had all of the dust removed therefrom. After passing through this door the fiber is deposited upon a conveyer band 64 whichis driven by any suitable means 64a for carrying away the cleaned. fiber. rlhis .ber after passing through this dust removing process may beV Vmade up into twine.

From the arrangement thus far described it is seen that fiber picked up from around the variousliber treating machines is thrown into the pit 35, carried into the shaker by conveyer band 36, the fiber shaken on shal ing members 14 and 15 from which it is passed automatically, by the thrusting action of shaking member 15, into the picker 11 where all remaining dust is removed, after which the ber passes through the picker door onto the conveyer 64, from which it may be collected to beV made up into twine.

Heretofore there has been no accurate and well-timed relation between the operation of the shaker and the opening' and closing` of the picker discharge door 63. Due toithis fact, in many instances dust laden fiber from the shaker has been passed into the picker at the time the discharge door was opened, resulting in the discharge of fiber from which the dust has not been thoroughly =re inoved. To overcome this undesirable feature, we have provided the shaker and picker with timing and control mechanism which operates in a manner such that the shaker is permitted to operate only at a time when the discharge door of the picker is closed,A the opening and closing of the Vpicker discharge door and the ope-ration of the shaker being controlled automatically. his control mechanism includes a relatively large gear 65 which meshes with a smaller gear 66,v

mounted upon a stud shaft 67 upon which lift:

also is mounted a sprocket wheel 68 over which passes a chain 69 which is actuated by a sprocket wheel 70 mounted upon one end of shaft 49. The gear wheel 65 is secured to 4a sleeve portion 71 of a cam member 72 having an internal cam surface 73 which is engaged by a roller 74 mounted in one end of an arm 75, which arm is secured to a shaft 76 mounted in bearing members 77 secured to the frame of the picker l1. Secured to the shaft 76 are two arms 78 each having a yielding connection to the discharge door 63 by means of slotted links 80 and resilient members or springs 81. As shown in Fig. 4 during three-quarters of a revolution of the cam member 72 the roller 74 takes a circular path, during which time the door 63 is maintained in a closed position, and during the other quarter of the revolution of the cam 72 the roller 74 engages the elongated portion 7 2a of said cam, during which time the discharge door 63 is being opened and closed. Also secured to the sleeve 71 of the cam member 72 is a second cam 82 (see Figs. 4, 5, 6 and 7) the surface of which is engaged by a roller 83 mounted in one end of a pivotally mounted lever 84, to one end of which is connected a link 85, which is connected to a belt shifter 86 through the medium of an arm 87, rod 88 and arm 89. rlhe belt shifter is provided with the usual projecting member 90 for engaging the belt 23. To the shifter is connected a spring 91 tending to shift the belt onto the tight pulley 22 and to force the roller 83 into the notched portion 92 of thecam 82. It is to be noted that the notched portion of the cam occupies about one-fourth of the periphery of the cam 82, corresponding to the relative duration of operation of the shaker, the remaining threefourths of the periphery of the cam 82 being circular. When the roller 83 passes into the notched portion 92 of cam 82 the belt shifter is caused to shift the belt onto the tight pulley 22, whereupon the shaking members 14 and 15 are actuated until the roller 83 passes out of the notched portion and onto the circular part of the cam 82. By referring particularly to Fig. 4 it will be noted that with the cams 72 and 82 in their full line positions, the picker discharge door 63 is opened and that as the roller 74 passes upwardly on the right hand side of the elongated cam portion 7 3 the roller 83 will approach the notched portion 92 of the other cam 82. Just at the point where the roller 74 reaches the circular part of cam 72, at which time the discharge door 63 has been completely closed, the roller 83 passes into the notched portion 92 of cam 82, at which time the shaker is started into operation. This position of the cams is shown in dotted lines in Fig. 4. As above stated, the shaker continues in operation during the following quarter revolution of the cams 72 and 82,

during which time the fiber is transferred automatically from the shaker into the picker, the wheels 55 of the picker being operated continuously for removing any dust which may be in the liber. During the following half revolution of the cams 72 and 82 the shaker is held in a state of rest and the discharge door 63 of the picker is held closed, the picker wheels 55, however, being continuously in motion. At the end of this last half revolution the roller 74 has reached a point 93 on the cam 72, at which point the roller 74 is about to drop down the elongated portion of the cam 72 due to the weight of the arm 75 for opening the discharge door 63 to permit fiber to pass therethrough onto the conveyer 64. It sometimes happens that the discharge door becomes wedged in itsI closed position and the weio'ht of the arm 75 under such conditions is notl sufficient to open the door. To overcome this we have provided an arm 94 which is secured to shaft 76 and to which is pivotally connected a link 95 having a hooked portion 96, which is adapted to be engaged by a projection 97 extending from the gear65 into the path of said hook. 1f it should happen that the door became wedged and would not open under the influence of theweight of arm 75, projection 97, just after the roller 74 has passed point 93 of the cam 72, will engage the hook 96 drawing the link 95 to the right as shown in Fig. 4 for forcefully opening the door 63. the hook 96 then being raised out of engagement with projection 97 by the link 95 engaging the bottom of the slotted portion 98 of a guide member 99 secured to the picker frame. By means of this hook and projection arrangement the door cannot remain in -closed position even though it became wedged. At the same time when the door is wedged, the door cannot be broken in any manner whatsoever for the reason that the yieldable connection is provided between the said door and the arms 78.

By means of this control mechanism which is associated with the picker, it is seen that the shaker is caused to operate intermittently at times only when the discharge door of the picker is closed, and the opening and closing of the discharge door of the picker and the operation of the shaker are automatically controlled. In this manner it is impossible. for fiber to pass through the discharge door 63 `without first havin the dust thoroughly removed therefrom. t is to be noted that due to the belt connection 24a the feed controller 34 is controlled simultaneously with the shaker proper; that is, when the shaker is in operation the feed controller is in operation and when the shaker is at rest the feed controller is at rest.

It is apparent that there may be various modifications of our invention as particularly herein described and shown, and it is CII our intention to cover all such modications which do not involve a departure from the spirit and scope of our invention as set forth in the appended claims.
